摘　　要：We report an all-fiberized chirped pulse amplification system without any bulk devices.The stretcher and compressor are chirped fiber Bragg gratings inscribed in a 6/125μm single-mode fiber and a 30/250μm largemode-area fiber.The fabrication system of chirped fiber Bragg gratings was designed and built by ourselves.The width of the linear exposure spot was controlled according to the different fiber sizes to improve the fabrication quality,and the parameters of chirped fiber Bragg gratings were fine-tuned during the fabrication to achieve the overall system’s spectral matching.Two fiber circulators with the same fiber sizes as the chirped fiber Bragg gratings were employed to auxiliarily achieve the pulse stretching and compression.The dispersion accumulations provided by the stretcher and compressor are 129.8 ps and 90.8 ps.The power amplifiers were composed of the two-stage 10/130μm fiber pre-amplifier and the 30/250μm fiber main amplifier.The proposed chirped pulse amplification system with no spatial light is the true sense of an all-fiberized chirped pulse amplification structure and shows the main trend in development of ultrashort pulse fiber lasers.
